STOVE.

Specification of Letters Patent.

Patented July 2, 1907.

Application filed April 12, 1907. Serial No- 367,760-

To all whom it may concern:

Be it known that I, JOHN A. BREEN, a citizen of the United States,residing at Utica, in the county of Oneida and State of New York, haveinvented certain new and useful Improvements in Stoves, of which thefollowing is a specification, reference being had therein to theaccompanying drawings.

My invention relates to an improved stove, and I declare that thefollowing is a full, clear, concise and exact description thereof,sufficient to enable one skilled in the art to make and use the same,reference being had to the accompanying drawings in which like lettersand numerals refer to like parts throughout.

The invention has to do particularly with cook stoves and has referenceto the method of constructing the oven. As stoves have heretofore beenmade the parts which together form the oven-box have been made of asingle sheet of cast iron which has been liable under expansion orcontraction to break, or to become loosened from its connected parts,necessitating extensive repairs or interfering with the perfectoperation of the stove. It has also been customary to support thetop-plate of the stove on this oven top by means of lugs or legs whichfrequently become loosened and drop out leaving the top-plate withoutsupport which warps and bends when highly heated. Various otherconstructions have been used for forming the oven and supporting the topthereon. I

I have produced a construction which obviates these difliculties andrenders the stove more durable, as well as less expensive.

In the drawings, Figure 1 is a perspective view of a part of a stove, aportion of it being broken away and showing in a general way theconstruction of the oven. Fig. 2 is a sectional view of two of theplates, showing one method of forming the joint; while Fig. 3 shows amodified joint. Fig. 4 is a sectional view of an oven side or top madeof an integral piece formed with the ridge therein. Fig. 5 is an edgeview of two plates with the edges turned up in a flange, somewhatexaggerated, indicating how the plates may be assembled at the edge ofthe top and the sides, for instance.

My invention includes the making of the top, sides or bottom of the ovenof rolled or pressed metal sheets or of cast iron, adapted to be securedin place in the frame of the stove in any suitable or usual manner. InFig. 1 I show the ridge formed in the top, sides and bottom of the ovenas running in a front and rear plane, but it will be understood thatthis plane may be given any direction. 1

Eachportion of the oven (except in this case the back and the door)consists, in one form, of plates A arranged in pairs, each pair formingone wall and having the adjacent edges of the members in each paircurved upward. In Figs. land 2 one upturned edge is shown wider than theother and lapping over the top edge of the adjacent plate. The curvededges thus united extend up far enough to form of themselves a supportfor the top-plate of the stove, and also means for supporting the ovenon the lower portions of the stove frame and maintaining the oven andthe side walls in proper relative and supported position; while also theridge on the top forms a firm support for the top-plate of 'the stove,which, therefore, prevents its settling and warping under the pressureof heavy utensils and when highly heated. Plates may be thus assembledto form the top alone of the oven, or to form any of its walls, or allof the same, as may be desired or found ex-' pedient. An importantfeature of such construction of an oven is that it permits freedom ofexpansion and contraction and removes strain from the joints in the ovenwalls, and that the greatest strength may be secured with economy andsimplicity of construction.

For the purpose of allowing for expansion and contraction, the platesare curved at their edges (1 to form a ridge, as indicated in theseveral figures. It is not, of course, essential that the plates shouldbe separate,

7 and in Fig. 4 it is seen that a single plate may be used having aridge rolled therein. If the plates are separate they may be united attheir edges by a bolt or other suitable means, as indicated by a in Fig.3.

I do not, of course, limit myself to the details of construction or asto the particular kind of joint made between the plates or where onewall joins another, as it is within the skill of the mechanic to makesuitably tight joints.

In brief, the invention consists in an oven whose walls are made up ofparts connected in a ridge, or walls formed of an integral member with aridge formed therein, the said portions or walls being made of thinmaterial so connected and formed as to provide sulficient strength withlightn ss of material and provision for expansion and contractionunder-heat, and to form interbearing supporting means between the ovenand the frame and other parts of the stove.

Having described my invention, what I claim as new and desire to secureby Letters Patent, is:

1. In a stove, an oven top comprised of a plurality of parts curved attheir adjacent and connected edges to form viding inter-bearing andsupporting means between the oven and the adjacent construction of thestove.

4. An even Wall of rolled material formed with a trans verse ridgetherein, havingan outwardly curved base, the ,ridge extending outwardlyto contact with the adjacent stove construction.

5. An oven top formed of rolled material formed with a transverse ridgethereon, having an outwardly curved base, the ridge extending upwardlyto support the stove top.

6. An ovenv having wall portions bent outwardly in :1 ridge, thewalls ofthe said ridge flaring near the base to take up expansion andcontraction in the oven walls, the

said ridge providing a support for the adjacent; walls 01' the stove.

T. An oven construction having plates hent upwardly in a ridge, thewalls of the said ridge flaring outwardly near the base and the saidridge providing a support for the adjacent walls of the stove.
